Rodriguez has some great bikes to offer for every style of riding. My favorite is their "Eight-Ball" which is a tandem that can be easily disassembled into two tidy 26 x 26 x 10 packing cases that can be then taken on a trip far, far away and then reassembled into either the tandem, or if your tandem partner is a little too tired to ride that day, you can assemble it into a single and ride off by yourself. Nifty.
Not only can you take the bike with you, but you also avoid all those excessively high
being charged for regular bike frames these days because those 26" x 26" x 10" storage boxes are deemed to be luggage sized - not freight, by airlines the world over. Luggage always travels for free or is less expensive by far.
If I had a wish list of three completely different bikes I could have. I would have
build them all custom - just for me. Seattle made, real steel, awesome.
